Congenital right subclavian artery aneurysm resection in a 30-year-old woman

Abstract

Right-sided subclavian artery aneurysms (SAAs) are exceedingly rare. The most common cause of intrathoracic SAAs is atherosclerosis; however, causes can also include infection, trauma, cystic medial degeneration, Marfan syndrome, and Takayasu arteritis. Symptoms present most commonly with compression of surrounding structures, although adverse events, including rupture, thrombosis, and embolization, can also occur. We present a case of a 30-year-old woman with an asymptomatic, 15-mm, right-sided SAA, which was successfully resected with subsequent end-to-end primary anastomosis.
